Graphite electrode is mainly used in electric arc furnace to heat the furnace charge. Graphite electrode, also known as graphite carbon material, has different quality indexes to adapt to various working environments. Today we talk about the advantages of graphite electrode.
The advantages of graphite electrode are easy to process, high metal removal efficiency and small graphite loss. Therefore, more and more mold factories abandon copper electrode and use graphite electrode instead. In addition, some shapes of electrode can not be made of copper, but graphite is easier to form, and copper electrode is heavier, which is not suitable for processing large electrode. These factors accelerate the application of graphite electrode in mold manufacturing industry more and more widely. Graphite electrode is easy to be machined. For example, the machining speed of graphite by milling process is 2-3 times faster than that of other metals, and no additional manual processing is needed, while copper electrode needs manual grinding. Similarly, if high-speed graphite machining center is used to make electrodes, the speed will be faster, the efficiency will be higher, and there will be no dust problem. The design of graphite electrode is also different. Many mold factories usually reserve different amount for rough machining and finish machining of copper electrode, while graphite electrode uses the same amount of reserve, which reduces the number of machining. For this reason alone, it is enough to improve the accuracy of mold cavity to a large extent.
In practice, it is found that the processing speed of graphite electrode is 58% faster than that of copper electrode, the processing time is greatly reduced, and the manufacturing cost is also reduced. Therefore, many factories are using graphite electrode, which can improve the competitiveness of enterprises and products.
